Hi,

with the FlashPro version 4.0.7 following feature was added:
[2017-2021 FK8 Civic Type R] Added another turbo temperature limit table (2019+ only)

Sorry if the question is dumb, but what is the purpose for the second table? Both table use IAT2, so which one is used on the calibration?

Those two pics are from the base 93 octane map And if i reupload an older calibration which is locked from my tuner, does the new added second table cause problems? Or is it necessary that my tuner have to edit the turbo temperature limit table #2?

This new table is also visible in the calibrations for 2018 FK8 Europe

It is a turbocharger maximum pressure ratio table based on intake temperature and rpm in order to limit the discharge temperature of the compressor.

There already is one table to perform this function; the additional table has the same use but will be used under different conditions.

Is it normal, that the table #2 has lower values?

I talked with my tuner and he checked out my map telling me, that the new table #2 has drastically different values.

He also said, when he opens a calibration for an us-market fk8 the table values are matching. But not for my europoen-market fk8 calibration.

Just tested with some basemaps and it seem i find the problem:

FK8 2019 US - 93 Octane Basemap seems to work. Both values are identical: But the FK8 2020-2021 US and all FK8 EU (2019-2021) have different values on the tables
I also choose the 93 Octane Base Maps for this. But all other calibrations i tried have the same results.
Can you confirm this?

I don't see any problem.

The table was added. The values are whatever Honda/Bosch set them to be. We cannot change those values initially because then it would alter peoples calibrations.

Ok, so this table was always there on the ecu but not yet able to edit with FlashPro.

My calibration should work with the same boost now (4.0.7) as with prior hondata versions, and i have not to change the values on the second turbo limit table, right?

Still wonder what condition cause the ecu to use the second map instead the first one? Do you have more details about this topic?

Yes, you summary is correct.

I'm not sure where (or if the) other table is used.
